摘要
提出了一种基于单向函数的满足动态安全性的组播密钥分配方案,比较了其与OFT方案的不同特点,使用该方案在组成员加入或退出时只需更改节点公开信息,减少了密钥更新所需的广播消息量,结果表明,该方案具有较高的可行性。
This article gives a new multicast key distribution scheme satisfying dynamic security based on one-way function. Using this scheme the key distribution tree needs only changing a few of its key nodes public announcing information when group members join or leave the group. Thus this scheme improves the rekeying efficiency of the key distribution tree. Furthermore, this article compares this scheme with OFT scheme, the results show this scheme is practical.
